This year’s #NobelPrize laureate in physics Anne L’Huillier discovered that many different overtones of light arose when she transmitted infrared laser light through a noble gas. Each overtone is a light wave with a given number of cycles for each cycle in the laser light. They are caused by the laser light interacting with atoms in the gas; it gives some electrons extra energy that is then emitted as light. L’Huillier has continued to explore this phenomenon, laying the ground for subsequent breakthroughs.

A round of applause! Students and colleagues at @lunduniversity came together to recognise newly named physics laureate Anne L’Huillier. Drop a 👏 in the comments to congratulate our new Nobel Prize laureate. Video credit: Nina Ransmyr, Lund University

Dedicated teacher alert! Not even the 2023 #NobelPrize in Physics could tear Anne L'Huillier from her students. Our new physics laureate was busy teaching a class. During a scheduled break, she heard the news. After the phone call, L'Huillier went right back to her students.
